“God also said to Moses, ‘Say to the Israelites, ‘The Lord, the God of your fathers – the God of Abraham, the God of Isaac and the God of Jacob – has sent me to you’. This is my name for ever, the name by which I am to be remembered from generation to generation’”. 

Ex 3:15 NIV 

One of big questions in the Christian faith is the baffling one of why God chose to work through this small tribe of wandering Israelites when there were bigger and more powerful and successful nations that he could have used. Then the questioners have to face the fact – he did, however irrational it might seem to us. 
“Right through the Bible the distinguishing mark of God’s earthly people is their knowledge of a self-consistent God who speaks by his word and allows them to know his unchanging name. This was so when there was only Adam: the hall-mark upon his life was that he possessed the word of God to obey, and his privilege as the tenant of the garden was conditional upon his living by that word. Again, what distinguished Abraham and the patriarchs from their Canaanite contemporaries was not that they were emigrants from Mesopotamia but that they were in Canaan because God had spoken to them and made them his word-bearers” (A. Motyer, The Message of Exodus, p71). 
The church of Jesus Christ has become the trustee of God’s word today. It bases its life, its worship and its witness on that same word – including the incarnate word in Christ. Make sure your church community places the message of God in the centre of all it does. So that God can reveal himself through it anew in every age. 

Lord, keep your church ever mindful of its primary calling.
